A channel and delay estimation algorithm for both positive and negative delay, based on Paprika the distributed Alamouti scheme, has been recently discussed for base-station-based asynchronous cooperative systems in frequency-flat fading channels.This paper extends the algorithm, the maximum likelihood estimator, to work in frequency-selective fadi
The main goal of every development plan is to achieve economic growth and mass production with considerations for the needs of economy and optimal utilization of resources and capital in the Decanters society.Urbanization is one of the most important aspects of the modern society, which embodies significant factors that can lead to economic growth.
Free Space Optics (FSO) Communication has attracted the attention of the researchers in the last decade due to its high data rate, security, and low cost.Relay-assisted techniques are used to divide the distance to shorter hops in order to mitigate the effects of turbulence, weather attenuation, pointing error, and geometric loss.Choosing an active
The reparative and regenerative capabilities of dental pulp stem cells (DPSCs) are crucial for AFTER SUN SOOTHER responding to pulp injuries, with protein phosphatase 1 (PP1) playing a significant role in regulating cellular functions pertinent to tissue healing.Accordingly, this study aimed to explore the effects of a novel cell-penetrating peptid
